- jersey, on 10/12/2007, -1/+108All titles exposed ? Why dont these companies just fold, and give us what we ask for ? We'll buy it if it isn't DRMed to hell, but if it is, we'll get around it, and take it for free.
- Netcruzer, on 10/12/2007, -2/+75Here is the Processing Key which should work on all HD DVD discs (and maybe even Blu-Ray discs) released so far:
Code:
09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0
Save it. Store it.

arnezami - Netcruzer, on 10/12/2007, -2/+45Again, from the Doom9 Forums. Some of you are missing the true meaning of this compromise. If they revoke this processing key, we just take a player compatible with a new processing key, put in one of the titles that's already cracked, and go around in memory looking for the known key. We find it, insert a new title, look in the same place and we have a new processing key.
- Sarki, on 10/12/2007, -25/+65Nothing new here, dupe.
http://digg.com/software/Today_s_BIG_news_is_the_REAL_destruction_of_DRM_on_HD_DVD - Warblade, on 10/12/2007, -1/+36If you're so concerned about extras, you COULD just buy the damn thing. You're complaining that the illegal free thing you got isn't as good as the thing you would actually have to pay for. You just got a movie for free, stop complaining.
- podgey22, on 10/12/2007, -3/+34"It's been broken for a while."
Technically incorrect. There have been workarounds (namely software memory dumping from legitimate player software) to expose the keys. This is different because it's a master-key that doesn't require a legitimate player in the first place.
Who knows, this might allow for a viable open source player application so people can watch these things on Linux boxes. - wonboodoo, on 10/12/2007, -0/+24Excellent work arnezami. A great win for free culture, and two thumbs up for sticking it to the man.
- bromac, on 10/12/2007, -0/+21From the man himself, on Doom9 forums:
"But this for now: the Processing Key and/or Device Keys of a player were already compromised before this thread even started. Keep your facts straight. I started this topic knowing AnyDVD had already done it. But that was not the only reason. Will explain more later.
Please concentrate now on doing something constructive. Like trying to build sniffing software, giving more Volume IDs, getting Blu-Ray C-values/Validate Media Key etc.
Regards,
arnezami"
He wasn't the first, and even he admits it. - Netcruzer, on 10/12/2007, -0/+20Blu-Ray is also decryptable with this Processing Key. It has been confirmed on the Doom9 forums. :D
- jersey, on 10/12/2007, -0/+18Question is, how long until they change it? But hell, even if they do, it will be cracked soon after.
You would think they would get tired of being owned day after day. - EatingPie, on 10/12/2007, -2/+19This is an AACS exploit specifically. It completely compromises HD-DVD, but NOT Blu-Ray.
Blu-Ray has two additional levels of copy protection.
One is a ROM-MARK, which is assigned per duplication plant, and must be present for a disk to be played. For *widespread* piracy -- ie, wholesale duplication in China for example -- they must find a way to duplicate / exploit the ROM-MARK. BUT, this doesn't effect individuals, since (from what I understand) you can still "de-AACS" a Blu-Ray and burn it to a BD-R, which does NOT require a ROM-MARK for playback. So backup of Blu-Ray is still possible via a BD-R burner even with ROM-MARK present.
The second is BD+, which has NOT been placed on any Blu-Ray to date. I've read reports that say it's now finished (gee I wonder why), and will start appearing this year. This is another encryption layer, and will require cracking just like AACS did.
-Pie - mattvogt, on 10/12/2007, -2/+18Shhhhhhhhhhhhhhhhhh, they'll hear you.
- Buelldozer, on 10/12/2007, -1/+13They're hosed. Even if they somehow obfuscate the key in memory of a software player, or stop authorizing software players all together, there are STILL a lot of *hardware* hackers out there with the skill to get things done. :)
- chembro84, on 10/12/2007, -0/+12When will these guys learn, there is no way in hell they are going to stop people from doing what they feel is right, it's quite clear that people hate DRM. We love hi-def, but we're not willing to give up all the rights of our media to these people to get it, I will not buy a DRM'ed title, and I am glad that it's been cracked, because now I don't have to.
- DorkmasterFlek, on 10/12/2007, -0/+12I hope they do just that. The backlash from consumers would be huge. Lots of people have media PCs that they use in their entertainment centres that rely on commercial software players. It's just being output to their TV instead. This wouldn't stop the hackers at all, they'd just come up with players of their own or another way of extracting the key from the disc. All it would do is piss off legitimate users and further entrench their hatred of these ridiculous DRM schemes. I say bring it on. They're only ensuring the downfall of DRM.
- wtf00, on 10/12/2007, -1/+11love this war against DRM. everytime I see DRM got ***** I get smile in my face.
- ZackS, on 10/12/2007, -1/+10It's a shame this happened so soon and with a software player. If we waited until a popular, not easily upgradable set top player gained some traction, then stole the key from there, this crack would not only give us unencrypted content but also cause the MPAA to lose face over the whole key revocation nonsense. Anything to make it hit home with grandma. That way, they might even not revoke the key to prevent a consumer riot.
- bromac, on 10/12/2007, -1/+10It's a lot harder to sniff a key off a chip than out of a memory register.
- inactive, on 10/12/2007, -3/+11That's the whole point of the revocable keys badbox. They pull the keys, the compromised titles no long play (or the compromised devices no longer work).
The problem isn't that things would break (at least to the MPAA). The problem is the bad will that would be generated by everybody who purchased the player/title, didn't do anything but enjoy the movie under the terms given, then had everything pulled out from underneath them. They aren't going to blame 'those damn haxors'. They are going to blame Best Buy, or Paramount, or Gods forbid, the MPAA!!! - m3mnoch, on 10/12/2007, -1/+8from the blu-ray assn's site:
"Sony, by appointment by the above Blu-ray Disc Association Board of Directors as the Blu-ray Disc License Entity is responsible for Blu-ray Disc Information Agreement (IA) and Blu-ray Disc License Agreement."
sony is the keeper of the license. sony shoulders the dev burdon. sony makes the royalties. the other companies are stooges.
no. sony doesn't own blu-ray, but they "own" it.
m3mnoch. - vaga222, on 10/12/2007, -1/+8If this continues I guess the MPAA will stop giving software players the AACS licenses and power DVD will no longer be able to release new players. While I feel for them if that was to happen I would be amused that MS embedded DRM into the core of Vista just for some spotty kid in a basement to kill the only reason for the vast majority of the copy protection.
- DorkmasterFlek, on 10/12/2007, -2/+9Exactly. There is no such thing as an unbreakable DRM scheme. It's theoretically impossible. Anything created by humans can be bypassed by humans.
- Slovell, on 10/12/2007, -2/+8Some people are missing the point. DRM is not to prevent people from copying, hackers will always find a way, the studios no this. The purpose of DRM is to lock the average consumer into a content stream. The average consumer will then purchase multiple formats of the same content, which is what the studios want.
- ranumm, on 10/12/2007, -1/+7Wow you really didn't read the forum, did you?
- xrisnothing, on 10/12/2007, -0/+6Yeah, right. I know when I'm ripping DVD's from netflix, if there's no DRM on the disc, I run out and buy it ASAP. Oh but if there is, I pull out AnyDVD and get to rippin'.
- RyeBrye, on 10/12/2007, -1/+7Yeah, and if they can 'crack' you a firmware that makes a magic robot appear and build a new laser necessary to read the BR discs you are hoping your other firmware update would make playable - then you might be all set!
- bromac, on 10/12/2007, -1/+5Note: it's not that this method will not work.
It's the fact that it's a method that this form of encryption is designed to combat. They will issue a new Media Key, and blacklist certain device keys. I wouldn't doubt that the studios may even blacklist software players altogether, until they find a way to better obfuscate or encrypt the keys while they are in memory. - jull1234, on 10/12/2007, -1/+5...and security through obscurity loses again.
- bromac, on 10/12/2007, -0/+4Or, they think the software (which is what is the issue here) is a problem, and then they go and buy a set-top player which plays the movies just fine.
I don't think they'll blacklist all the launch titles...but it's trivial to blacklist WinDVD and PowerDVD. - JESUSREAM, on 10/12/2007, -4/+7When the burners are down to $100 and the discs are $2 ill be all over it.
- bromac, on 10/12/2007, -1/+4And, then they revoke the device key you sniffed off the hardware, or issue another Processing Key.
Unless you sniff enough hardware device keys to make recalls unfeasible. But, I don't think we have the manpower for that.
Sniffing the Volume Unique Key avoids this mess. You have what you need to decrypt the movie.
@ AbortedFetus:
You think I'm some sort of MPAA schill? I'm all for cracking DRM. I'm also for PROPER understanding of these encryption systems, and their capabilities, not some "OMG WE BEAT THEM!!!" useless rhetoric. - KissTheRing, on 10/12/2007, -0/+3The current mini processor (1.83 Ghz core duo) is the same as what I have in my iMac Core Duo (not Core 2 Duo) and it plays 1080p h.264 content just fine. I know the HDD isn't as fast in the mini (although I plan to stream content over a gigabit network) but what else would cause the current mini to not be able to play a HD movie (BTW I'm likely not going to use h.264, I'd prefer Xvid, which plays with less horsepower. But I still think that it will play 1080p h.264 video)
Could those of you who say it doesn't play for you list the specs of your machine, and anyone who can play 1080p h.264 videos on their mini also list your specs. - bromac, on 10/12/2007, -3/+6@podgey22
This is a "workaround", if you're going to be picky about language, too. Do you "workaround" passwords too? It does not crack AES. They sniffed the Media Key out of memory just like the Volume Unique key. It's a very similar method to the old one.
And it breaks AACS just as well as the old method, for the time being. If I could download decrypted protected content last month, how is it not broken? The DRM wasn't doing it's job, hence it was broken. - kethraal, on 10/12/2007, -0/+3"anyone who can play 1080p h.264 videos on their mini also list your specs."
Sure.
Mac Mini 1.83Ghz Core Duo, 1G RAM, 7200 RPM HD, using VLC. - bromac, on 10/12/2007, -3/+6Why is everyone telling me it's not impossible? Where did I say that?
I said it was HARD, meaning it was indeed possible. - Zybergod, on 10/12/2007, -0/+2You can pick up the DRM t-shirt here:
http://www.cafepress.com/dlkmadsen.129054705 - postmaster3000, on 10/12/2007, -0/+2"it would be great if there could be a function to do all the heavy lifting for this built into Handbrake or the new offshoot MediaFork so that it's no different than processing DVDs."
Yes, that would be called AnyDVD-HD. Coming soon, it will automatically strip AACS protection from any HD-DVD disc transparently to the player. So you'll even be able to play a disc with vanilla MPC or VLC. - Buelldozer, on 10/12/2007, -2/+4@bromac,
Hardware is harder, in some ways, but CERTAINLY not impossible. There's a lot of bored Engineering Students out there with access to labratories chock full of expensive test and analyzation hardware. :) - Gundam, on 10/12/2007, -0/+2The discs I buy are 16 cents a gig. 2 dollars for a Blu-Ray blank disc is 8 cents a gig, they are currently 40 cents a gig. 5 bucks a disc is arguably more realistic/
- spoonyinc, on 10/12/2007, -1/+309 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 forever!
- vastrightwing, on 10/12/2007, -1/+3Excellent point. I think that Encryption is designed to lock manufacturers into paying a royalty so they can build DVD players and the studios make money from the hardware manufacturers. Encryption does not prevent people from copying.
DRM, was intended to allow publishers to sell the same content over and over on multiple devices and platforms. This would be like making a book readable only by a unique individual. Imagine a book publisher selling a printed book which could only be read be one person. This goes back to the days when books were hand copied and only a few people could read anyway.
I say, the publishing industry should convict Gutenberg for inventing a way to mass duplicate copywriten works. Gutenberg would have obviously loved P2P technology or invented it him self. - KissTheRing, on 10/12/2007, -0/+2If either Sony or Toshiba revokes any keys now they run the risk of losing any foothold they have currently. Whoever is the first to revoke a key, Blue-ray or HD-DVD, will be the one who loses the format war.
- ArchonSG, on 10/12/2007, -1/+3@EatingPie
All the more reason not to buy Blu-Ray.
I don't need more DRM "capable" crap. Don't support it, don't want it and sure as hell won't pay good money so that I can be put on a "jump through these hoops if you want to watch our crap" circus show that these "content owners" seem hell bent on making us all do.
In the end, it'll be worked around for sure since it doesn't matter if you put the best locks on your door as long as you need to leave keys in the open (any legitimate player) for people to find. Which is what DRM really is, an inconvenience to everyone except those making money off it.
Eventually someone high up enough from one of the two groups will realize that its futile and a waste of time and release the "flawed" versions or even DRM broken versions just so that it'll reach critical mass and become the dominant format. - AggieTales, on 10/12/2007, -0/+2RE:"anyone who can play 1080p h.264 videos on their mini also list your specs."
my mini has:
1.83GHz Core Duo, 1 GB RAM, 7200 RPM 80GB HDD
and plays back 1080p H.264 at a constant 30 fps, no issues, using Quicktime Pro (only about 60-70% CPU utilization) - publicanemone, on 10/12/2007, -2/+4congratulations arnezami!
- bromac, on 10/12/2007, -0/+2The problem with that is that the easily sniffed keys come from software players. Which do not cost $800+.
- laser314, on 10/12/2007, -0/+2I don't' see the Average consumer blaming "Best Buy, or Paramount, or Gods forbid, the MPAA!!!." They will blame the the HD-DVD or Blue-Ray player. The manufacture of the their set-top box. "Damn machine, only had it three months months and its already broke. They just can't make crap that lasts anymore." The average consumer knows nothing of encryption or revocable keys and cares even less. If the MPAA Really wants to crack down it would require a new format that is ONLY available on set-top boxes, taking the PC out of the loop. As long as
it is playable on a PC it will be cracked. - jdavid, on 10/12/2007, -0/+1it will be a sad day for the hacker community when DRM is replaced with quantum key infrastructures.
at defcon someone once said, that if you can design something right the fist time than you do not need any tools to know how it works, but if you make mistakes along the way, and you need to discover those mistakes, then you must create tools to discover how it works, and as such you create the tools for someone else to discover how it works and how to copy it circumvent it.
the current set of DRM is not absolute security, it is just a time sink, much like the lock on your homes door. anyone can get past it with knowledge and effort, and if someone whom with you did not invite enters your home, well, you might have a problem with that. however, the problem with DRM is that most of the time it will not let you into your own home, and I HAVE AN EVEN BIGGER PROBLEM WITH THAT.
If i buy a movie, i should have the right to put it on any electronic device i own! I should buy the right to show it to any reasonable number of friends and family, provided i am not profiting from it. If i want to profit from a showing, i should easily be able to acquire those rights, it should be INSTANT, and it should be included on any player, from an ipod, zune, replayTV, TIVO, DVD, HD DVD, xbox360, and blu-ray players. If i pay for something as a pay per view, it should let me what it once anywhere, even if i start watching it on one device and finish it on another.
What we need are a set of consumer bill of DRM rights. We have rights toooooo, not just the copyright holders. From what I know, DVDs were cracked with decss because there was not a linux player, so he made one anyway he could. If DRM advocates want it MAKE IT FRAKEN transparent, MAKE IT FRAKEN simple. I do not want to pay extra for a digital version if it means that in a fire or a hard drive failure i have to buy it again.
WE need to change the culture now, before DRM actually works with tech like quantum keys. - bsmsmbaphd, on 10/12/2007, -0/+1HD-DVD code leaked on purpose to kill Sony Blu-Ray format.
- CompIsMyRx, on 10/12/2007, -0/+1I love that after every DRM comes out as "uncrackable", it is completely broken within a few months.
